Vector form of Newton’s Law of Gravitation Newton’s Law of Gravitation states that everybody in this universe attracts every other body with a force which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them. Consider two points mass bodies A and B of Read more about Vector form of Newton’s Law of Gravitation[…]
